Wasn't it revealed way back when Polyphony first announced GT4: Mobile that many features would be removed to make the PS2 version definitive? Is this still how things will be, or did I miss something along the way? My apologies if I did, as I've not exactly been keeping up with news about this game. In fact, to be honest I nearly wrote it off as vapourware! However, that's not to say my opinion has changed (much) since most people - myself included - are now looking forward to the next real chapter of this series...
Well the fact that it's very unlikely you're going to be able to play the game with a steering wheel is probably the biggest example of why the PS2 version is the definitive version.
I expect the PSP version to be more than just GT4:Lite. Otherwise the port would not be taking this long to complete.
Why are games so obnoxiously expensive outside of the US and Japan? Anyway, I'll definitely buy this when it comes out. I love all things PSP. I play the hell out of mine, mostly MGSO recently but also lots of other titles. I still need to pick up Medal of Honor though.....
